Be it known that I, ALAN$ON P .-Bnnsn, a citizen of. the vUnited. States, residing at Detroit, county of \Vayne, State of Michigan,'have invented a certain new'and useful novel spring suspension mechanism adapted accompanying drawings, in which,

for a variety of uses, the same being of: superior construction and utility, and 1t consists of the ,mechanism hereinafter described and clalmed and illustrated ,in the Figure 1 is a view in side elevation. Fig. 2 1s a. plan vlew. -F1g. 3 1s a rear elevation.

" Fig. 4 is a .view in section on the line ek -4,

The aim offmy device is to provide an improved spring. suspension mechanism for frame work indicated at a, in the drawings.

suspending, for example, a supporting I have shown my improved device applied to a vehicle in which b represents an axle, and c a radius rod enga 'ed therewith. The

' axle is shown suspende upon a rod d,- said rod passed through a bracket 1; attached to the supporting frame work, upon which bracket is located a coiled spring 7 the rod dat its upper end. being engaged with the upper end of the spr ng in any suitable manner, as' by a'washer 'g and nuth. The forward end'of the radius rod is connected with a bracket/z engaged withsthe frame,

the adjacent end of the radiusjrod c being formed with a hub tojournal in the bracket 2', as indicated more particularly inFig. 4, the hubof the radius rod being engagcd in the correspondingly formed portion of the bracket 2', a washer j intervening. The radius rod maybe pivoted-on the bracket 71 The bolt lathe in any suitable manner. I. friction washers jand l, the frlctlon plate m, and the spr ng washer p form a frictlon device for retarding thoscillation of'tlie radius rod about itsgournal on the bracket i. I would have it'understood that I do not limit myself to any particular form of friction device, however, nor do I'limit my inthough for certain conditions a friction dei vention to'the use of any friction device, al-

will be understood that the radius rod is rigidly engaged upon the axle.

arranged so as to take the torsion of the axle,

.allowing only avertical movement offthe axle, in other words the radius rod is so arranged as to -resist any torsion of the axle It will be observed that the radius rod iscausedby turnin corners onthe front wheels ofavehlcle, an on the rear wheels by the action of a brake,- or by driving mechanism. The radius rod is so arran ed as to maintain the axle n position lateizilly or'sldewise as well as longitudinally of the vehicle, allowing to the axle only the proper vertical movement. By arranging the radius rod in this manner I am enabled to use a coiled that a coiled spring, under certain conditions of roads or under certain driving conditions, would have altogether too much rebound, the same having toormuch elasticity, but

But it is well understood this I overcome by making the joint of theradius rod where it pivots on the trainee friction device, the ,same being preferably adjustable, so that any desired amount of simply tightening up the bolt '70, which has .so I friction may be maintained'at thatpoint'by, 1 i

a threaded engagement in the bracket i, as

indicated at 1', Fig. 4. 'Byso doing the frictional effect decreases the-rebound of the U spring. vA coiled spring-it is well understood, has morecapacity in proportion to its weightthan a flat spring and I overcome its too great elastlolty, under'ccrtain conditlons, by the frictional arrangement of the rad us rod in its jointed engagement with the frame:

"By the mechanism above described I am en; abledto got an degree of friction deslred;

It will be evident thatthe 3 rings sustain the \veigl1t- 'of.the frame an ran ed to expand and contract.
